Today I renewed the bypass filter in the Ram 3500
I had to remove it to work on the turbo and exhaust manifold.
It was very black oil slimy feeling oil on the paper surfaces and basically I had to pull it and unroll it from the center.
The new filter paper is packed tighter this time, still had to unroll a bunch to force into the housing.
Oil enters the bottom center, flows up and out over the top, then filters down through the TP and drains out the bottom.
The smaller tube keeps the spring pressure down on the big center tube, which has a washer on the bottom. The TP roll is a tight fit. The bottom of the big tube has a 3/8 tall spacer to exactly fit the inner paper roll. I can barely blow thru it from inlet to outlet
